Yes, the subsystem ID is different [1] (but Zotac program it the same as the vendor and device IDs here), however what you say suggests the problem is general to this Etron XHCI controller (1b6f:7023), as we'd suspect anyway. Thus the more general patch I posted makes better sense perhaps? Thanks, Daniel --- [1] # lspci -vs 02:00.0 02:00.0 USB controller: Etron Technology, Inc.
